Another plus the AllPro heads have is they use the HIP heat treating process

Hot isostatic pressing

Hot isostatic pressing (HIP) is a form of heat treatment that uses high pressure to improve material properties. Castings for critical applications are HIPed to eliminate internal microporosity thereby improving mechanical properties by removing defects
